PaperFlow – E-book Reader

PaperFlow is an e-book and comic reader built so the book on the screen feels like paper. The corner lifts where your finger lands, folds, and turns. Everything else stays out of the way of reading.

■ What it reads
• EPUB and TXT — typography set against the real page: size, line spacing, letter spacing, glyph width, margins, indents, with presets of your own
• PDF
• CBZ, CBR and ZIP comics — double-page scans recognised, split or trimmed, right-to-left books, webtoon scrolling

■ Pages that behave like pages
• GPU-rendered page curl that follows your finger, dog-ears, riffling
• One or two pages by the shape of the screen — a foldable shows a spread open and a single page closed
• Fit to page, width, height or fill
• Paper, parchment, newsprint, forest and slate themes, an e-ink mode, OLED black

■ Read aloud
• Your device's voice reads any book. The sentence being spoken is inked on the page and the page turns to follow.
• Pro: a high-quality neural voice that runs on the device, no internet needed; an AI that skips footnotes and captions and gives each character in a dialogue a voice of their own; a handwriting marker that writes each letter stroke by stroke.
• A sleep timer (10 to 60 minutes, the end of the page, the end of the chapter, fading over the last minute), picking up at the sentence you stopped on, and a pronunciation list for names and abbreviations.
• The neural voice and the AI judge run on the phone. The only time PaperFlow sends a book's words anywhere is to an online voice (Google, Qwen) you turned on with your own API key.

■ The same place on every device
• Reading positions sync through Google Drive, Dropbox, OneDrive or a folder you choose.
• Compatible with KOReader sync servers, including Komga.
• Bookmarks, highlights, reading records and settings back up to the same place.

■ Your library, wherever it is
• Device folders and SD cards
• Pro: WebDAV, SMB (NAS) and OPDS catalogues (Calibre-web, Komga, Kavita, Ubooquity) — open books straight from the server without downloading, index a shelf and search it

■ Privacy
• No account, no developer server. Books and reading records stay on the device; only the sync you turn on talks to the service you chose.
• No analytics or crash-reporting SDKs.

■ Free and Pro
• Free: every format, the paper page turn, read-aloud with the device voice, cloud and KOReader sync, backup. Banner ads appear only where books are chosen and settings made, never over a page being read.
• Pro: no ads, the neural voice with its AI judge and character voices, network shelves, Pro themes, your own fonts. Try Pro free for three days, then for 24 hours with each ad you choose to watch.
